In the U.S., a 2-32 is about the only thing available.
Not only the per seat restrictions of 110kg for most modern glass gliders. You have the "Max wt of the non lifting" part of the glider.

I didn't say it was a good thing and you're correct, you can't solo from there.
The other issue (at least in a 2-33) is control movement. A "larger sized" person (not totally related to weight, but also posterior) could spread the cockpit sides enough to jam the rear rudder pedals.

Really, for a prospective pilot, would be to slim down some.

Not picking on anyone, glad to see someone asking valid questions. Jon S., good luck in your pursuit of flying. No sarcasm intended.
